                           instructions given to the Company at least two (2)
                           business days prior to the Closing Date.

                  Section 2.  Closing. The Closing shall take place at the
principal offices of the Company at the date and time of the closing (the "CTS
Closing") of the transactions contemplated by the CTS Agreement or if the
Company, at its option, elects to consummate the transactions contemplated
hereby thereafter and prior to a termination as provided in Section 11, at such
other date and time as is designated by the Company by at least five (5) days'
advance written notice to Seller. Such event is referred to as the "Closing" and
such date and time are referred to as the "Closing Date." If the CTS Agreement
is terminated, either party may terminate this Agreement as provided in 
Section 11.

                  Section 3.  Termination of Employment at Closing.

                  (a) Until the Closing Date or termination of this Agreement
pursuant to Section 11 hereof, Seller shall be considered to be on vacation from
his position with the Company. He shall receive pay during such period as if he
were on vacation until he has fully utilized all of his accrued and unpaid
vacation, at which time he will be deemed to be on paid leave from his
employment with the Company. The Company shall not terminate Seller's employment
during such vacation and paid leave.

                   (b) Subject to receipt by Seller of all of the payments
described in Section 1 hereof and delivery of the promissory note as described
in subsection (c) below, Seller hereby resigns effective on the Closing Date as
an employee and/or consultant of the Company and from any and all positions,
directorships and offices Seller may have with the Company. The Employment
Agreement (the "Employment Agreement") dated as of January 6, 1996 between the
Seller and the Company and any and all other agreements or arrangements whereby
Seller has been employed by or provided services to the Company shall be
terminated as of the Closing Date. In the event that this Agreement is
terminated for any reason, Seller's employment with the Company shall be
unaffected by this Agreement. In addition, in consideration of Seller's
termination of his employment with the Company, as described in this subsection
(b), the Company releases Seller, effective as of said termination, from any and
all of the terms and conditions of the Employment Agreement relating to
non-competition and/or non-interference. Said release shall not affect Seller's
obligations under Section 6 hereof.

                  (c) In further consideration for the agreements of Seller set
forth in subsections (b) and (d) of this Section, the Company will deliver to
Seller on the Closing Date a Promissory Note (the "Note") in the form attached
as Exhibit A.

Erbe and the Company's stockholders, directors, officers, employees, agents,
representatives, successors and assigns (the "Related Persons") on the one hand,
and Seller on the other hand, from any and all obligations arising from all
agreements with respect to Seller's employment with the Company or Seller's
provision of services to the Company, whether written or oral, including but not
limited to, the Employment Agreement. Seller on the one hand, and the Company
and Erbe on the other hand, hereby release and forever discharge, effective on
the Closing Date, any claim Seller on the one hand, and the Company and Erbe on
the other hand, may now have, or may hereafter have, in connection with Seller's
employment or the termination of his employment with the Company. Seller on the
one hand, and the Company and Erbe on the other hand, hereby confirm and agree
that it is Seller's intention on the one hand, and the Company's and Erbe's on
the other hand, by this release to release, effective on the Closing Date, the
Company, Erbe and the Related Persons on the one hand, and Seller on the other
hand, from any and all claims, demands, damages, actions, suits of any and every
nature, known or unknown, relating to Seller's employment with or provision of
services to the Company to the date of this release, including, but not limited
to, claims arising under federal or state statutes or common law, for breach of
contract or for incentive compensation, bonuses, vacation or severance pay.
Notwithstanding the foregoing, this release shall not release any party from its
obligations under this Agreement or the Note.

                  (e) If either party terminates this Agreement pursuant to
Section 11 hereof, all the provisions of this Section shall thereafter be of no
further force or effect.

                  (f) Until the Closing Date, nothing in this Section shall be
deemed to release or waive, or to constitute an admission with respect to, any
rights of Seller against or with respect to the Company or Erbe on the one hand,
or any rights of the Company and Erbe against or with respect to Seller on the
other hand, or the Employment Agreement or the Stock Redemption Agreement, as
defined below.

                  Section 4.  Escrow of Shares.

                  (a) On the date hereof, Seller has deposited the stock
certificate evidencing the Shares and a stock power endorsed by Seller in blank

escrow agreement in the form attached hereto as Exhibit B (the "Escrow 
                                                ---------
Agreement") among the Seller, the Company and the Escrow Agent.

                  (b) Seller shall retain all voting rights and rights to cash
dividends and distributions with respect to the Shares and all rights and
interests of any kind and nature whatsoever in the Stock Redemption Agreement,
as defined below, and in any other agreement relating to the Shares until the
Closing and until the Note and all payments payable pursuant to Section 1 have
been received by Seller.

giving the Escrow Agent written instructions to release the Certificate and
Stock Power to the Company.

Agreement. The terms of the Stock Redemption and Purchase Agreement (the "Stock
Redemption Agreement") dated as of February 6, 1991 among Seller, the Company
and Erbe are hereby waived to the extent they in any way conflict with or
prohibit any action taken or transaction consummated or to be consummated
hereunder. Subject to the receipt by Seller of all payments described in Section
1 hereof and delivery of the Note, Seller shall have no further obligation or
right under the Stock Redemption Agreement. Seller consents to the execution and
delivery by Erbe and the Company of the CTS Agreement.

individual purposes or those of another, contact or communicate with any
employee of the Company without regard to his/her location, for the purpose of
attempting to or actually soliciting or hiring that employee on Seller's own
account or on the account of another.

                  Section 7.  Seller's Representation and Warranty. The Seller
represents and warrants to the Company that, except for certain restrictions on
the sale of the Shares under that certain Stock Redemption Agreement, which,
subject to the conditions described in Section 5 hereof, have been effectively
waived and released, he is the owner, free and clear of any liens, options,
pledges, encumbrances, security interests or other claims (collectively,
"Liens"), of all of the Shares and that, upon release of the Certificate and
Stock Power to the Company, the Company shall receive good title to the Shares,
free of any and all Liens.

                  Section 8.  Company's Representation and Warranty. All
necessary action has been taken to authorize execution and delivery hereof by
the Company and its consummation of the transactions contemplated hereby and the
execution, delivery and performance of this Agreement are not in violation of
the Company's governing documents or any other document to which it is a party
or bound, nor do they require the consent or approval of any party that has not
been obtained.

                                       4.
